 <p>This test is similar to simple-stateless, with two major differences. In this case all the classes are regular POJOs without annotations.
 The EJB-specific metadata is provided via an XML descriptor. The second difference is the explicite use of Local and Remote interfaces. </p>

 <h2>CalculatorImpl</h2>

 <pre><code>package org.superbiz.calculator;

 /**
  * This is an EJB 3 stateless session bean, configured using an EJB 3
  * deployment descriptor as opposed to using annotations.
  * This EJB has 2 business interfaces: CalculatorRemote, a remote business
  * interface, and CalculatorLocal, a local business interface
  */
 public class CalculatorImpl implements CalculatorRemote, CalculatorLocal {

     public int sum(int add1, int add2) {
         return add1 + add2;
     }

     public int multiply(int mul1, int mul2) {
         return mul1 * mul2;
     }
 }
 </code></pre>

 <h2>CalculatorLocal</h2>

 <pre><code>package org.superbiz.calculator;

 /**
  * This is an EJB 3 local business interface
  * This interface is specified using the business-local tag in the deployment descriptor
  */
 public interface CalculatorLocal {

     public int sum(int add1, int add2);

     public int multiply(int mul1, int mul2);
 }
 </code></pre>

 <h2>CalculatorRemote</h2>

 <pre><code>package org.superbiz.calculator;


 /**
  * This is an EJB 3 remote business interface
  * This interface is specified using the business-local tag in the deployment descriptor
  */
 public interface CalculatorRemote {

     public int sum(int add1, int add2);

     public int multiply(int mul1, int mul2);
 }
 </code></pre>

 <h2>ejb-jar.xml</h2>

 <p>The XML descriptor defines the EJB class and both local and remote interfaces.</p>

 <pre><code>&lt;ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"
          version="3.0"&gt;
   &lt;enterprise-beans&gt;
     &lt;session&gt;
       &lt;ejb-name&gt;CalculatorImpl&lt;/ejb-name&gt;
       &lt;business-local&gt;org.superbiz.calculator.CalculatorLocal&lt;/business-local&gt;
       &lt;business-remote&gt;org.superbiz.calculator.CalculatorRemote&lt;/business-remote&gt;
       &lt;ejb-class&gt;org.superbiz.calculator.CalculatorImpl&lt;/ejb-class&gt;
       &lt;session-type&gt;Stateless&lt;/session-type&gt;
       &lt;transaction-type&gt;Container&lt;/transaction-type&gt;
     &lt;/session&gt;
   &lt;/enterprise-beans&gt;
 &lt;/ejb-jar&gt;
 </code></pre>

 <h2>CalculatorTest</h2>

 <p>Two tests obtain a Local and Remote interface to the bean instance. This time an <code>InitialContext</code> object is directly created,
 as opposed to getting the context from <code>EJBContainer</code>, as we did in the previous example. </p>

 <pre><code>package org.superbiz.calculator;

 import junit.framework.TestCase;

 import javax.naming.Context;
 import javax.naming.InitialContext;
 import java.util.Properties;

 public class CalculatorTest extends TestCase {

     private InitialContext initialContext;

     protected void setUp() throws Exception {
         Properties properties = new Properties();
         properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");

         initialContext = new InitialContext(properties);
     }

     /**
      * Lookup the Calculator bean via its remote home interface
      *
      * @throws Exception
      */
     public void testCalculatorViaRemoteInterface() throws Exception {
         Object object = initialContext.lookup("CalculatorImplRemote");

         assertNotNull(object);
         assertTrue(object instanceof CalculatorRemote);
         CalculatorRemote calc = (CalculatorRemote) object;
         assertEquals(10, calc.sum(4, 6));
         assertEquals(12, calc.multiply(3, 4));
     }

     /**
      * Lookup the Calculator bean via its local home interface
      *
      * @throws Exception
      */
     public void testCalculatorViaLocalInterface() throws Exception {
         Object object = initialContext.lookup("CalculatorImplLocal");

         assertNotNull(object);
         assertTrue(object instanceof CalculatorLocal);
         CalculatorLocal calc = (CalculatorLocal) object;
         assertEquals(10, calc.sum(4, 6));
         assertEquals(12, calc.multiply(3, 4));
     }
 }

	<p>This test is similar to simple-stateless, with two major differences. In this case all the classes are regular POJOs without annotations.
	The EJB-specific metadata is provided via an XML descriptor. The second difference is the explicite use of Local and Remote interfaces. </p>

	<h2>CalculatorImpl</h2>

	<pre><code>package org.superbiz.calculator;

	/**
	* This is an EJB 3 stateless session bean, configured using an EJB 3
	* deployment descriptor as opposed to using annotations.
	* This EJB has 2 business interfaces: CalculatorRemote, a remote business
	* interface, and CalculatorLocal, a local business interface
	*/
	public class CalculatorImpl implements CalculatorRemote, CalculatorLocal {

	public int sum(int add1, int add2) {
	return add1 + add2;
	}

	public int multiply(int mul1, int mul2) {
	return mul1 * mul2;
	}
	}
	</code></pre>

	<h2>CalculatorLocal</h2>

	<pre><code>package org.superbiz.calculator;

	/**
	* This is an EJB 3 local business interface
	* This interface is specified using the business-local tag in the deployment descriptor
	*/
	public interface CalculatorLocal {

	public int sum(int add1, int add2);

	public int multiply(int mul1, int mul2);
	}
	</code></pre>

	<h2>CalculatorRemote</h2>

	<pre><code>package org.superbiz.calculator;


	/**
	* This is an EJB 3 remote business interface
	* This interface is specified using the business-local tag in the deployment descriptor
	*/
	public interface CalculatorRemote {

	public int sum(int add1, int add2);

	public int multiply(int mul1, int mul2);
	}
	</code></pre>

	<h2>ejb-jar.xml</h2>

	<p>The XML descriptor defines the EJB class and both local and remote interfaces.</p>

	<pre><code><ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"
	version="3.0">
	<enterprise-beans>
	<session>
	<ejb-name>CalculatorImpl</ejb-name>
	<business-local>org.superbiz.calculator.CalculatorLocal</business-local>
	<business-remote>org.superbiz.calculator.CalculatorRemote</business-remote>

	<session-type>Stateless</session-type>
	<transaction-type>Container</transaction-type>
	</session>
	</enterprise-beans>
	</ejb-jar>
	</code></pre>

	<h2>CalculatorTest</h2>

	<p>Two tests obtain a Local and Remote interface to the bean instance. This time an <code>InitialContext</code> object is directly created,
	as opposed to getting the context from <code>EJBContainer</code>, as we did in the previous example. </p>

	<pre><code>package org.superbiz.calculator;

	import junit.framework.TestCase;

	import javax.naming.Context;
	import javax.naming.InitialContext;
	import java.util.Properties;

	public class CalculatorTest extends TestCase {

	private InitialContext initialContext;

	protected void setUp() throws Exception {
	Properties properties = new Properties();
	properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");

	initialContext = new InitialContext(properties);
	}

	/**
	* Lookup the Calculator bean via its remote home interface
	*
	* @throws Exception
	*/
	public void testCalculatorViaRemoteInterface() throws Exception {
	Object object = initialContext.lookup("CalculatorImplRemote");

	assertNotNull(object);
	assertTrue(object instanceof CalculatorRemote);
	CalculatorRemote calc = (CalculatorRemote) object;
	assertEquals(10, calc.sum(4, 6));
	assertEquals(12, calc.multiply(3, 4));
	}

	/**

	*
	* @throws Exception
	*/
	public void testCalculatorViaLocalInterface() throws Exception {
	Object object = initialContext.lookup("CalculatorImplLocal");

	assertNotNull(object);
	assertTrue(object instanceof CalculatorLocal);
	CalculatorLocal calc = (CalculatorLocal) object;
	assertEquals(10, calc.sum(4, 6));
	assertEquals(12, calc.multiply(3, 4));
	}
	}
